The third stage of the historic Haute Route leads from the Cabane de Saleinaz (2691 m) over the Col de la Grande Lui (3419 m) into the Val Ferret to La Fouly (1595 m). The route links the glaciated high mountain landscape of the Mont Blanc massif with an exceptionally long descent into the deeply cut Swiss Val Ferret.
This stage is characterised by the alternation between demanding cols and wide glacier slopes. The steep climb to the Col de la Grande Lui in particular requires solid alpine skills. Then a descent of around 1800 m awaits, all the way to La Fouly, provided the snow cover allows a continuous ski run.
